This will be the first time the Padres have been in Coors Field since the 163rd game of last season, when the Rockies rallied in the 13th against Trevor Hoffman to win 9-8 and advance to the National League playoffs as the wild card team.

A half-season later, the teams will be playing and trying to avoid last place in the NL West and possibly the worst record in the majors.

The Rockies have lost seven straight, the Padres eight straight. The teams are 3-3 head-to-head this season, all at Petco Park.

Maddux hasn't won in nine starts since defeating Colorado on May 10 for the 350th victory of his career. He is 15-8 in 28 starts against the Rockies and 7-2 at Coors Field with a 7.21 ERA.

The nine starts without a win is the second-longest such stretch of Maddux's career. He went winless in 13 straight starts with the Cubs in 1990. He is 0-3 over his last nine starts with a 3.44 ERA. The Padres are 5-4 in those nine starts.
